"Eat... Are you kidding me? Can you really eat this thing? It's as hard as a stone. Whether it can be digested or not is a question, and it's only natural to get sick after consuming it. Moreover, Heart of the Universe is so hard and big, how can I eat it?" Green looked at Heart of the Universe in confusion.

However, the other person just smiled faintly. "Of course you can eat it, it's just a bit hard."

"You're so proud, what are you trying to do?"

"Nothing much, I'm just wondering if making the other version of myself in another world show this expression counts as 'still a young talent'."

"..."

Green looked speechlessly at "himself". It must be said that they really resembled each other in certain aspects. No, they were originally the same person, just with different experiences.

But... as a normal human who has been eating cooked food for so many years, isn't it too much to suddenly be expected to eat something that is not even considered food and can't be digested?

"Do you really want me to eat this thing? Chew it in my mouth and swallow it into my stomach?"

"Yes, just like how you normally eat, just swallow it."

"..."

As if sensing Green's doubts, the other person smiled lightly and continued, "This thing is energy. Once it enters your stomach, it will automatically convert into energy that your body absorbs. Didn't you just say that your physique has become much stronger? Eating this thing shouldn't be a problem, but there is one thing you need to pay attention to."

"What is it?"

"The energy inside here is the power of the origin. The reason why the rules of the world eliminate powerful beings like gods is mainly because they possess self-awareness, which pure energy is incapable of having. Therefore, the world rules only eliminate intelligent life forms but do not eradicate or eliminate pure energy.

However, once you absorb the energy into your body, its nature becomes completely different from before.

I've mentioned before that superpowers are derived from the power of the world's origin. In other words, if you completely absorb this unknown power of the origin, you might awaken some new abilities.

And that's where the problem arises.

The more powerful you become in that world, the more likely you will become a target to be eliminated by the world rules.

But since such a large piece of source energy crystal can be created, and there are even gods existing, it means that the power of the origin in your world hasn't been fully unsealed, so the safety barrier is still quite high. If nothing unexpected happens, I don't think there will be any problems, but it is still advisable for you to prepare mentally."

"Mm..."

Green fell into deep thought after listening, and the other person didn't disturb him.

After hearing "himself" explain, Green also remembered Aloof and their world, where the overall strength was much lower compared to the world of superpowers, and magic and mana couldn't be compared to source energy.

Perhaps the upper limit of safety strength in that world was really high.

But the key was that Green felt that ever since he became the Demon King, his strength, in the fully unlocked state of superpowers, was stronger than when he first arrived in Aloof's world.

It was far stronger than when he consumed a large amount of source energy to save the world. Therefore, Green was still somewhat worried. As the other party said, if he absorbed the power of the world's origin and awakened a bugged ability, wouldn't it be destined for him to be eradicated by the rules of the world? The concept of world rules alone seemed incredibly complex.

"By the way, what made you so free that you had to remodel the demon realm? Isn't it better to just be a couch potato?"

"I've been lazing around for a long time. It's mainly because after becoming the demon king, I developed some inexplicable feelings for the demon realm and had this desire to make it better."

"Oh..."

The other person calmly took a sip of water and remained neutral.

The two of them sat on rough stone benches, watching the people around them with smiles on their faces. Some were celebrating the earth's survival, while others were working hard to clean up the rubble, basking in the sun for the afternoon.

Until Green felt his buttocks becoming uncomfortable, he took out a chair from his personal space.

"Ah – you sneaky guy, you've been hiding things!"

"What are you talking about? I just forgot to take it out earlier."

"Tsk... But you don't need these things, right? Can you give me some?"

"Sure."

Afterward, Green took out many tools from his personal space. Although these things were not very useful to Green, they could still be helpful to this rebuilding world.

Green then expressed that he needed to go back and carefully consider whether to consume the Heart of the Universe.

As evening fell, he prepared to leave and return. The crowd put on bandages and came to see Green off. Although it may not be an overly touching gesture, it still made Green feel that saving this world was not without meaning.

"If you have time, remember to come... to play!"

"Just now, you meant to say patrol, right..."

"How could that be, you misunderstood."

Green sighed, feeling that this world was full of disaster. He was genuinely worried that one day he might not be able to find it anymore.

"Well, I'm leaving now, bye."

"Wait!"

Just as Green was about to leave, a crisp voice suddenly called out to him.

Green looked towards the source of the voice and saw his daughter in this world. He vaguely remembered her name was Grily, a very awkward name... Randomly assigned to the S-tier degree.

"What's wrong?"

"Muah~"

A gentle and delicate feeling brushed against his cheek, and Green immediately realized that he had just been kissed by the other person.

Grily blushed, looking at Green with a shy smile and whispered in a soft voice, "Thank you for saving this world once again!"

Then she took a few steps back and waved at Green.

"See you next time!"

"Yeah!"

Under the gaze of everyone, Green released the vast source energy within him, easily tearing through space and stepping into the pitch-black chaos stream.

Before long, Green returned to his original world.

During dinner, Green shared the information he gained this time with his wives without hiding anything.

Aloof first raised his hand to express his opinion. "I choose to support Green's idea. Anyone else?"

Everyone raised their hands, surprisingly unanimous in their opinions. Although Green had anticipated this result, experiencing it firsthand still warmed his heart. It was evident that they were sincere, which was exactly what Green had hoped for. A harmonious family with no conflicts was the best outcome.

"Well then, I'll choose to consume it," Green said. However, when he took out the Heart of the Universe, he couldn't imagine how he would actually eat such a large piece of stone. Biting directly into it? No, that wouldn't be elegant. Preparing it as a dish? That wouldn't work either, as Green had never seen stone used as an ingredient in cooking.

In the end, it seemed that biting into it was the only viable option. Green stared at the Heart of the Universe, trying to showcase his own elegance. Finally, summoning his courage, he opened his mouth wide and bit down hard on the Heart of the Universe.

"Crack!"

There was a sound of something breaking. Green was startled and quickly took a step back, examining the situation closely. It turned out to be a false alarm. He had thought that his tooth had cracked, but instead, the surface of the Heart of the Universe had unexpectedly cracked in numerous places.

"It's not as hard as I imagined..."

With the experience of the first bite, Green became more proficient the second time. Another loud crack and a piece of the Heart of the Universe was bitten off by Green. Once it was inside his mouth, Green chewed it as if it were ordinary food. Surprisingly, besides its intimidating appearance, the Heart of the Universe actually tasted quite good.

The texture was exceptionally crisp, and when Green got closer, he could hear the satisfying crunchy sound coming from his mouth. It didn't have much flavor, but it was still enjoyable.

Soon, the first bite was swallowed by Green. Aloof and the others looked at Green with concern and asked, "Are you okay? Do you feel any discomfort?"

"Well... not really, but I don't feel any changes in my body either. Maybe I didn't eat enough?" Green pondered, then took another bite. He quickly chewed and swallowed it, repeating the process.

After a few minutes, the outer layer of the Heart of the Universe was almost gone. Green also discovered, to his surprise, that although the Heart of the Universe was quite substantial in size, consuming it didn't provide any feeling of fullness. His stomach didn't even register its presence; it was as if it disappeared as soon as he swallowed it.

Seeing that Green appeared unaffected, Aloof and the others gradually relaxed. Elsa was the most worried, after all, Green had chosen to eat the Heart of the Universe in order to make the demon world better. As a member of the demon race, Elsa naturally cared deeply about the outcome.

Green increased his eating speed, now that he was certain there were no harmful effects. Swallowing became easier, and before long, only the final piece of the Heart of the Universe remained.

"Ah~ ooh~"

After inserting and swallowing the final piece of the Heart of the Universe, Green's body finally underwent a transformation.

First, a faint golden light emanated from his body surface, shining on everyone and creating a gentle and comforting sensation. Then, the golden light grew even more radiant and vibrant.

Soon, Green's entire body was enveloped in a dazzling golden glow, but the light quickly converged towards Green's head... no, more specifically towards his hair.

Before long, all the golden light from Green's body gathered above his hair.

Green's originally jet-black hair gradually turned into a light golden color, even his pupils and eyebrows changed along with his hair, giving him a completely different appearance.

At the same time, Green also discovered that his mind suddenly received some information.

Like when he first gained superpowers, an instinctive feeling was captured. When he tried to control it, he realized that he had changed significantly from before.

And now, Green could see the change in his hair color through his peripheral vision.

With a thought, his golden hair turned back to black.

After taking out a mirror and conducting multiple experiments, Green arrived at a bewildering conclusion.

It seemed that after consuming that piece of the Heart of the Universe, the ability he obtained was to turn his hair color into a luxurious golden shade...
